I very much enjoyed this. And very in keeping with the series, because I was just as confused about how it could be his first time when he didn't even know it was as I was about everything else when I watched the episode! Hee.
That was...well...I enjoyed it immensely I must say. I'm not really a porn person, but it was, in all seriousness, really spectacular. I think you did a wonderful job in exploring the relationship between the Doctor and River and in giving us something quite...readable. Bravo. I love River's character and I hope you write more with her.
About time some (hot) speculating with a very interesting idea. I love how the presence of River Song makes for mystery and debate. Good work.
Enormously readable. one *does* wonder at the relationship that the Doctor and River have - companion (the physical touching was a lot), companion with benefits, or ... It remains to be seen, but speculation is the point of fiction!
